Revolutionizing Transmission Technology for Electric Vehicles

In the world of EVs, the gear drive assumes newfound importance as an integral part of the electric motor driveline, constituting one of the three critical components of the EV power system, alongside the battery system and the electrical control device. Within this power system, the gear drive seamlessly integrates with the electric motor, yielding a lightweight and compact design.

Unlike traditional combustion engine vehicles, EVs operate solely on electric motors, eliminating the noise generated by combustion engines. Consequently, the performance of the gear drive becomes more noticeable, as it can no longer be masked by engine noise. This shift in focus amplifies the importance of gear drive in EVs.

The requirements for gear drive in EVs differ significantly from those of traditional transmissions. Consider the following contrasting features:

Gear drive for EV applications requires meeting stringent requirements to achieve optimal performance. The following aspects are of utmost importance for gear drive manufacturers in the market:

1.   Noise Reduction and Efficiency: EVs require a noiseless and efficient gear drive to enhance comfort and improve the vehicle's driving range. This necessitates a lightweight gearbox design with high ratios to ensure efficiency in high-speed electric engines.

2.   High Torque Gear Design:  Electric engines have unique torque characteristics, requiring gear drive designs that can handle high torque from the drive side as well as during recuperation.

3.   Noise Optimization: Gear drive must be designed to minimize noise across all load cases and speeds, given the absence of engine noise in EVs.

4.   Lubrication and Compact Design: Adequate lubrication principles must be employed for high-speed gear meshing, particularly in the first stage. Additionally, compact gearbox designs that integrate seamlessly with the electric engine are essential.

With the exponential growth of the EV market, the demand for high-performance gear drive technology is on the rise. However, traditional gear transmission manufacturing processes and measuring instruments frequently fall short of meeting the modern standards necessary for EVs. 

This is precisely where industry leaders, such as Klingelnberg, distinguish themselves.
